I'm guessing by device tree you mean the .dts file? I'm using a modified version of the mpc8313erdb.dts with minor changes (to the local bus only). Here is a copy of it./* * MPC8313E RDB Device Tree Source * * Copyright 2005, 2006, 2007 Freescale Semiconductor Inc. * * This program is free software; you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the * Free Software Foundation;
